Milwaukee RED COBALT HSS-G Co Metal Drill Bit Set, 1-10 mm, 19-piece

The drill bit heads are ground from a strong cobalt alloy high-speed steel with excellent heat resistance, in accordance with DIN 338 standard.
Suitable for drilling high alloy steel and metals with a tensile strength over 1000 N/mm⊃2;,⊃2;, such as stainless steel.
QUAD EDGE™ tip: a unique combination of a 135° split point and four cutting edges: the 135° split point allows for precise and fast drilling without walking. The four cutting edges create smaller chips to prevent heat buildup over time.
Variable drill bit working part geometry: for faster material ejection. Helps the tip work cooler and prevents it from burning out quickly.
Advanced tapering web: wider core towards the drill shank. Strengthens the core to increase the flute's overall durability.
Three-sided tail from ⌀ 5 mm, for a more secure drill bit attachment.
Color: bronze.
